3.75 Three lb of water is contained in a piston-cylinder assembly, initially occupying a volume V₁ = 30 ft³ at T₁ = 300°F. The water undergoes two processes in series: Process 1-2: Constant-temperature compression to V₂ = 11.19 ft², during which there is an energy transfer by heat from the water of 1275 Btu. Process 2-3: Constant-volume heating to pa = 120 lbf/in.² Sketch the two processes in series on a T-v diagram. Neglecting kinetic and potential energy effects, determine the work in Process 1-2 and the heat transfer in Process 2-3, each in Btu.

A fixed-mass system contains mass, m = 1.0 kg of air. A thermodynamic process occurs from state one to state two, where T₁ = 300 °K, P₁ = 100 kPa; T₂ = 2700 °K, P₂ = 204.9953251 kPa. Determine S₂ - S₁ = m (S₂-S₁) in kJ / °K. Note: You are required to assume constant specific heats in this problem, with Cpo = 1.004 kJ/(°K * kg); for air, the gas constant is R = 0.287 kJ/(°K * kg).

Could this be considered a thermodynamic cycle? Why or why not?
A fixed mass of gas undergoes changes of pressure and volume as shown below. V When the gas is taken from state P to state R by stages PQ and QR, 8 kJ of heat are absorbed by it and 3 kJ of work are done by it. When the same resultant change is achieved by stages PS and SR, 1 kJ of work is done by the gas. In this case which of the following represents the heat transfer? Select one: 8 kJ of heat are absorbed b. 4 kJ of heat are rejected 12 kJ of heat are rejected O d. 10 kJ of heat are absorbed
Air expands adiabatically in a piston-cylinder assembly from an initial state where p₁ = 100 lbf/in.², v₁ = 3.704 ft³/lb, and T₁ = 1000 °R, to a final state where p₂ = 30 lbf/in.²2 The process is polytropic with n = 1.4. The change in specific internal energy, in Btu/lb, can be expressed in terms of temperature change as Au = (0.171)(T₂ - T₁). Determine the final temperature, in °R. Kinetic and potential energy effects can be neglected. T₂ = i °R
